Personal experience. My series of 'Fast Corresp. 9x9 “Out-of-Ten”. Starts when full.
In an attempt to improve the quality of my tournaments, I have been kicking people who have TO’d out of two of the previous tournaments in the series or anyone that I know has a bad T.O. tendency.
I started getting more rigorous about it after this one: NovB which thankfully is not typical.
That said, there are only 5 people on my ‘banned from these tournaments list’ and only one of those makes repeated efforts to rejoin. Previously, miniond2 came to my attention in the same way, by endlessly trying to rejoin even while he was T.O.ing and not playing his other games.
It’s entirely possible that I am the only tournament director who attempts to improve tournaments in this way so if that is the case then it may be considered a ‘bug not worth fixing’.
Part of the reason for this post was to see if other TD’s had similar issues.
Conrad_Meliville and GreenAsJade have offered a reasonable alternative (if&when the time comes) which merely requires me to overcome my general reluctance to involve mods.
